Zhi Fu Zi - Bereide Aconietwortel - Radix Aconiti Lateralis Praeparata

Zhi Fu Zi (Bereide Aconietwortel) is een heet, bijtend en giftig kruid in de Traditionele Chinese Geneeskunde (TCM), dat sterk gebruikt wordt om verwoest Yang te herstellen, het binnenste te verwarmen en ingezakte Qi te redden. Het is de verwerkte zijwortel van Aconitum carmichaeli en één van de krachtigste Yang-verwarmende kruiden in de TCM farmacopeia. Zhi Fu Zi wordt vaak gebruikt bij koude extremiteiten, zwakke pols, instorting na ziekte, Yang-deficiëntie en ernstige koude-pijnsyndromen.
Alleen de verwerkte vorm (Zhi Fu Zi) wordt inwendig gebruikt, omdat rauwe Fu Zi zeer giftig is. Een goed afkooksel en deskundig toezicht zijn essentieel bij het gebruik van dit kruid.
